Nothing is perfect.
See? As soon as there's a good mod team that's gonna release something for rF, that mod has chances of becoming the most interesting package (considering they release both new tracks and cars as the original content is really bland in rF).
On the other hand, LFS isn't far from getting things right, but the problem is that it lacks in detail almost everywhere. LFS needs more sounds for example. It would also be nice to have textured tires sidewalls and BOLTED wheels (which apparently are super-glued or stuck with magnets ATM). It might also be nice to get some people in the grandstands, assigned pitboxes and garages per racer, pitcrews, sounds, and maybe some physics fixes.
I'm not gonna change to rF for the moment, but LFS better take some leaps in areas that help the feeling of real things soon.
We're already there with our leagues and teams and skins and events. Now just need a more immersive feel
